Re: Double Chicken Wire

No.  First shield at 5 ft from the chicken wire with second shield perhaps
another 8-12 inches back.   Use 1 or 2 ground stands to draw the arcs off
and provide a definite path for the arcs without hitting the chicken wire.

Hope they don't think you are going crazy at work.
